Usage

General Description

CHLOROETHANE-D5, also known as ethyl-d5 chloride, is a deuterated form of chloroethane, which is a colorless, flammable gas with a sweet odor. The "D5" in its name refers to the deuterium atoms, which are heavy isotopes of hydrogen. CHLOROETHANE-D5 is commonly used as a solvent, as well as in the production of other chemicals such as vinyl chloride and tetraethyl lead. It is also used in the pharmaceutical industry as a raw material for the synthesis of various compounds. However, it is important to note that CHLOROETHANE-D5 is considered hazardous, as it is a possible carcinogen and may have harmful effects on the environment if not handled properly.

Equilibrium Geometry and Vibrational Frequencies of the 1:2 van der Waals Complexes between Methyl Chloride and Hydrogen Chloride

The equilibrium geometry, relative stability and vibrational frequencies for the 1:2 van der Waals complexes between CH3Cl and HCl have been investigated using MP2/6-31 + G** ab initio calculations.The results are used to interpret the IR spectrum of the 1:2 complex observed in solutions of CD3Cl-HCl mixtures dissolved in liquefied argon, and show that in these solutions the chain complex CD3Cl*HCl*HCl is formed.

Orientational Behaviour of Phosphonic Acid Dialkyl Esters in Nematic and Smectic Phases of Pentoxy-benzylidene-hexylaniline Studied by 1H, 2H, and 31P NMR

The orientational behaviour of a variety of phosphonic acid diesters dissolved in different liquid crystalline phases of pentoxy-benzylidene-hexylaniline was studied.For the complete determination of the orientational ordering of the phosphonate segment, partially deuterated esters were synthesized and a combination of 31P, 2H and 1H NMR was used.For solutions of hexane phosphonic diethyl ester dissolved in the nematic and SA phases, the order parameter, S33 increases from 0.22 to 0.42 with a biaxiality of 0.1.The CH2P(O)O2 segment is in the trans-conformation and the S33 axis makes an angle of 22 deg with the P=O bond.In the SB phases the value of S33 of the phosphonate segment decreases dramatically to a value of 0.1 in contrast to that of the molecules of the matrix.The reason is that the solute molecules are excluded from the more ordered aromatic region and are forced into the less-ordered hydrocarbon chain region of the matrix.In the SG phase, a phase separation occurs.In diethyl esters with n-alkyl substituents, S33 increases with the chain length of the substituent.Keywords: spin labels, nematic ordering, smectic ordering, phosphonic acid derivatives, NMR.
